**app.ts**
```
import express from 'express';
import cors from 'cors';
import dotenv from 'dotenv';
import * as mongoose from "mongoose";
import apiRouter from "./router/apiRouter";

//Auto decouvrability
const hateoasLinker = require('express-hateoas-links');

export const app:express.Application = express();

app.use(express.urlencoded({
extended: true
}));

app.use(hateoasLinker);

// Configurations
app.use(cors());
dotenv.config( {path : './.env'}); // for env variable
app.use(express.json()); // json form data

let hostName:string|undefined = process.env.HOST_NAME;
let port:number|undefined = Number(process.env.PORT);
let mongoDBUrl:string|undefined = process.env.MONGODB_URL;

// MongoDB connection

if(mongoDBUrl) {
mongoose.connect(mongoDBUrl).then( () => {
console.log('Connecting to mongoDB Successfully ...');
}).catch( (error) => {
console.log(error);
process.exit(1); // Stop the node js process
});
}

app.get('/test', async (request:express.Request, response:express.Response) => {
response.status(404);
})

// Route Configuration

app.use('/api/v1/', apiRouter);

if(port !== undefined && hostName !== undefined){
app.listen(port, hostName, () => {
console.log(`Express Server is running at ${hostName}:${port}`);
});
}

module.exports= app;

```
